A 4x3 grid showcases twelve different trains from around the world, each rendered in bold, flat illustration style against colored backgrounds including hot pink, yellow, blue, green, orange, and purple. The composition celebrates global rail transport through a pop art sensibility, with clean lines, simplified forms, and a dynamic energy created by the contrasting hues and variety of locomotive and passenger car artworks. Printed on smooth white card stock and made to order, artwork on the front, blank inside, envelopes included in every set. A handwritten note that arrives as an independent artist's work.
